Keratitis or "pinkeye" in cattle is an infectious disease which infects cattle of all ages and breeds. It has a wide distribution and has been reported in Holland, South Africa, India, England and in parts of Canada. This disease has been recognized as a serious cattle disease in almost every part of the United States. Keratitis is not a new disease. It was recognized in Nebraska more than 70 years ago. Although the mortality is relatively low, the economic factor is great. Veterinarians and livestock owners readily recognize the importance of keratitis to the cattle industry.
